DETAILED DESCRIPTION I. Introduction

Current athletes work extremely hard to produce results and better themselves for competition. They desire to find devices that can track and monitor their physiological parameters to understand themselves and achieve better performance. However many current solutions offer insufficient information (only motion activity trackers, heart rate or some basic pulse oximetry). These current devices can offer insufficient review of meaningful data (just numbers and a basic trend graph). For further insights, athletes may draw their blood once, twice or three times in a year and review the information about certain parameters, such as their Total Hemoglobin Level. Many current systems offer only single peaks into a person's health and in many instances are incapable of giving insightful data review to make better training decisions.

Similarly, many competitive elite athletes go to extreme methods of training, such as living at high elevations or training at high elevations to achieve gains in their Total Hemoglobin levels. Some athletes even sleep in tents to simulate higher elevation at home. This determination and desire leads them to work this way based on published studies that provide general information, rather than an individualized understanding of the time it takes for their specific body to acclimate at different elevations. For example, a team of endurance cyclist could benefit by knowing at what point each of their members acclimates to certain elevations, at what elevation, and by how much. Accordingly, training, style, intensity and location could all be adjusted based on this information. Currently, invasive solutions offer insight into this information and would require an athlete to invasively test multiple times at multiple elevations to learn how they respond to elevation. Invasive procedures would be painful, expensive, and inconvenient (not mobile). Wearable and homecare technology (motion activity trackers, heart rate or some basic pulse oximetry, for example) cannot correctly complete a picture for when and how an athlete responds to elevation. Many wearable and homecare technologies do not provide insightful, intuitive and easy to use visual displays for communicating elevation effects.

In training, one of the struggles people face is to find daily motivation and understand how that determination positively or negatively affects them. Some traditional methods can use social interaction as a form of a support community and motivation to athletes. Many current solutions focus on social aspects solely to keep a user moving. However, many athletes are already active. Many current products help a user focus on a particular route an individual ran and/or the number of steps or elevation they climbed by using an inaccurate activity tracker. Some products allow integration of Heart Rate monitor statistics. However, many individual applications for physiological parameters and social sites fall short of providing valuable insight and comparison of blood parameters or the balance of blood parameters, environment, heart interaction on an individual level or compared to top athletic or Olympic levels.

Certain graphs disclosed herein, such as the trend graph and Yin-Yang display can offer the ability to filter the parameter and activity being displayed. This allows a user to choose to show resting measurements for particular days and only post some or all workout measurements. Thus, the user can filter certain results. The ability to filter can be advantageous because a user's hemoglobin value can vary drastically during a day, for example. In order for users to be able to see small seasonal variations, users can filter collected data to see the most stable and repeatable time of the day to measure, which could be first of day resting period. Similarly, the user can use the devices disclosed herein to determine the most stable and repeatable time of day to measure and view a resting pulse rate.

Advantageously, some embodiments of the system disclosed herein can allow the system to filter activity displayed in the graphs. In many instances, the system can be configured to allow a user to choose to display hemoglobin (tHb) or Pulse Rates (PR). Other parameters, including Functional and Fractional Oxygen Saturation, Oxygen Content, Carbon Monoxide, Methemoglobin, Perfusion Index, Pleth Variability Index, and/or Respiration Rate, among others, can be displayed through the system.

Alternative embodiments can include other visual focus and identification elements. In some embodiments, color and glowing effects can be used to indicate points at which the user's data reflects a significant change. In some embodiments, a user may see a 3d sphere that swells in size to reflect the climb in tHb values. In yet other embodiments of the system disclosed herein, additional lifestyle integration variations of sensors (such as bands, watches, shirts etc.) as well as variations on visual display to 3D augmented reality or heads up display units can be used. In some embodiments, the one or more graphs can add a multiple factor overlay. In this embodiment, the system can compare seasonal variation of atmospheric pollution levels with seasonal variations in the athlete's noninvasive CO readings or the seasonal variations in temperature with pulse rate. In additional embodiments, the system can compare elevation and tHb with the changes of atmospheric pollution levels as well as cross reference with multiple parameters. In additional embodiments, the system can compare Respiration Rate (Pleth acquired or acoustic or ecg acquired) compared with Heart rate and Pollen levels would let an athlete with respiratory conditions, such as asthma. Advantageously, embodiments of the system disclosed herein can allow a user to understand a balance of their respiratory system.

This disclosure describes embodiments of noninvasive sensor systems that can enable a user to view, compare, and/or information relating to the respiratory system, for example, via a computing device, which may contain more advanced functionality than traditional systems and devices. The computing device can be, for instance, a cellphone or smartphone, tablet, laptop, personal digital assistant (PDA), and/or the like.

For example, patterns or changes in the continuous noninvasive monitoring of intensity-derived information may cause the activation of other vital sign measurement devices, such as, for example, blood pressure cuffs.

II. Visual Multi Quadrant Infographic Display

Traditional methods of monitoring and displaying certain physiological parameters can lack the ability to monitor certain physiological parameters noninvasively. Traditional methods can take a long period of time to display collected data, including the physiological parameters. Rather, the systems disclosed herein can measure and display the physiological parameters within minutes. For example, embodiments of the system disclosed herein can frequently measure physiological parameters multiple times a day to build a substantial data set. The system can measure physiological parameters 1 to 2, 2 to 3, 3 to 4, 4 to 5, 5 to 6, and/or 1 to 6 or more times a day. In some embodiments, the physiological parameters can be displayed in an informative visual graphic display, such as a trend graph 230. The trend graph can be user-friendly and provide a well-designed display. For example, the trend graph can include a multi quadrant seasonal variation spider graph, as illustrated in FIGS. 2A-6C.

The trend graph 230 can provide a detailed look at all data points of the physiological parameters 203 within one or more seasonal years. In some embodiments, the trend graph 230 can display the physiological parameters 203 collected within one, two, three, four, five, six, seven, eight, nine, or ten or more years. Advantageously, the trend graph can allow the user to quickly and easily identify whether a seasonal variation exists in their physiological parameters.

Generally, users can have seasonal variation in several physiological parameters, such as tHb. As discussed above, the system 100 can collect user data 202 including information about a user at various intervals. The user data 202 can include a plurality of data points. For example, the system can measure and collect the data points at regular intervals throughout a period of time, such as an hour, day, month, and/or year. Advantageously, the system 100 can allow the user to track and assess user data 202 over time. For example, the system 100 can provide various points of comparison to the user through the user interface 200 so the user can make judgments based on all or a portion of the user data 202, rather than at a particular point in time. In some embodiments, it can be advantageous to measure, collect, and/or calculate the user data 202 at consistent intervals. In such configurations the system 100 can analyze more user data 202 to interpret a complete set of user data so that the system may interpret the user data 202 more accurately. In some configurations, the system 100 can provide user data 202 that can allow the user to make more accurate judgments about their physiological parameters. Accordingly, the user can have the ability to increase their performance based on more accurate results and adjust their diet and exercise routines. In some embodiments however, the system can measure and collect the user data at irregular intervals.

The user data 202 can include one or more data points corresponding to one or more physiological parameters 203. For each physiologic parameter 203, the system can assign certain information relating to each recorded physiologic parameter. For example, the system can assign a time, date, season, and/or location to each recorded physiologic parameter. Generally, the system can display information relating to the user data 202, such as whether seasonal variation occurs in a user's tHb and/or PR, when the variation occurs, and/or how the variation affects the user. In some embodiments, the user would be able to view the display information within seconds. Accordingly, the display information can help a user determine how to adjust a training routine and/or diet, for example, to achieve better performance results throughout the year.

The user can select from a plurality of filters and a plurality of physiological parameters. When the user selects a filter and a type of physiological parameter, the system 100 can display a user interface 200. The user interface 200 can be presented in an aesthetically pleasing and/or user friendly manner. The user interface 200 can display the user data 202, insights 206 and/or the one or more graphs 204 that allows the user to quickly view information. To view particular information, the user can select a filter from a plurality of filters. The plurality of filters can include filters that can dictate how the user data 202 is displayed, such as by season and elevation. In some embodiments, the user can select one or more physiological parameters 203. In some embodiments, the user can select an activity from the plurality of activities, such as pre-workout, pre-hydration, during workout, post-workout and/or post-hydration, among others. The user can select all activities from the plurality of activities. The system 200 can display the user interface 200 within approximately 500 milliseconds to 1 second after a filter is selected.

For example, a user can select a seasonal filter from the plurality of filters, a physiological parameter 203, and an activity from the plurality of activities. Upon the user's selection, the system 100 can display a user interface 200. FIGS. 2A and 2B illustrate an example of the user interface 200 in which the user has selected the seasonal filter. The user interface 200 can include a top navigation bar 208, one or more graphs 204, one or more insights 206, and a bottom navigation bar 212. The one or more graphs can include the user data 202 and the one or more physiological parameters 203.

The one or more graphs 204 can include the trend graph 230. The trend graph 230 can include a horizontal axis and a vertical axis. For example, the horizontal axis and the vertical axis can indicate the value of the physiological parameter 203 selected by the user.

The trend graph 230 can include a plurality of quadrants 234 to display the display information. In some embodiments, the trend graph 230 can include one, two, three, four, five, six, seven, eight, nine, or ten or more quadrants 234. For example, the graph 230 can include a first quadrant 234A, a second quadrant 234B, a third quadrant 234C, and a fourth quadrant 234D.

Each of the plurality of quadrants 234 can display information that corresponds to a particular seasonal time. The number of quadrants displayed in the trend graph 230 can depend on several factors, including a geographic location. For example, in geographic locations having four seasons, the trend graph 230 can include four quadrants associated with each of the four seasons. In the illustrated embodiment, the first quadrant 234A can correspond to Winter. The second quadrant 234B can correspond to Spring. The third quadrant 234C can correspond to Summer. The fourth quadrant 234D can correspond to Fall. In some embodiments, each quadrant of the plurality of quadrants 234 can be displayed in the same color. In some embodiments, each quadrant of the plurality of quadrants 234 can be displayed using different colors.

The user data 202 can be displayed in the trend graph 230 along a plurality of data rings 238. Each data point of the user data 202 can be displayed clockwise around a center of the data rings 238. In some embodiments, each data point of the user data 202 can be displayed counterclockwise around a center of the data rings 238. The data points can be presented in degree increments along the data rings 238. Each data point can represent a measurement taken and/or calculated by the system 100. For example, the system can record measurements of the user data 202 once a day. In this example, after 360 days, the trend graph 230 could display the user data 202 along a full ring of the data rings 238.

FIG. 3A illustrates an embodiment of a zoom user interface 250, which can display a close-up view of the trend graph 230. As shown in the FIG. 3A, the trend graph 230 can include a plurality of indicator rings 242 to illustrate various ranges and/or values corresponding to each particular physiological parameter 203 selected by the user. The plurality of indicator rings 242 can present an optimal range of physiological parameters 203. For example, the trend graph 230 can include a first indicator ring 242A of the plurality of indicator rings 242. The first indicator ring 242A can represent an optimal value for the particular physiological parameter 203 selected by the user. The optimal value and/or range can be based on one or more user inputs, such as the user's age and/or gender. The first indicator ring 242A can be disposed towards the center of the trend graph 230. The first indicator ring 242A can be disposed towards the outer periphery of the trend graph 230. The first indicator ring 242A can be disposed towards the inner ring of the trend graph 230.

In some embodiments, the trend graph 230 can include a second indicator ring 242B and a third indicator ring 242C. The second indicator ring 242B can indicate a lower value and/or range of the optimal range. The second indicator ring 242B can be disposed towards an inner ring of the trend graph 230 interior of the first indicator ring 242A, for example. In some embodiments, the trend graph 230 can include a third indicator ring 242C. The third indicator ring 242C can indicate an upper value and/or range of optimal range. The third indicator ring 242C can be disposed towards an outer ring of the trend graph 230 outwards from the first indicator ring 242A, for example.

Generally, the close-up view of the trend graph 230 can be presented to the user when the user activates one or more zoom user interfaces 250. Activating the zoom user interface 250 can allow a user to observe individual data points of the user data 202, among other detailed information displayed in the trend graph 230. The zoom user interface can allow the user to understand the user data 202 and gain a better understanding of how to adjust their diet and/or exercise routine, which can enhance the user's performance. The zoom user interface 250 can display information such as the time, date, season, and/or location assigned to each monitored, measured, and/or calculated data point.

When the zoom user interface 250 is activated, the zoom user interface can pop up from the user interface 200, overlap at least a portion of the user interface 200, and/or replace the user interface 200. To activate the zoom user interface 250, the user can apply a plurality of zooming gestures. The zooming gestures can include a double tap, a finger zoom, and/or a pan, among other gestures. For example, the user can double tap on the user interface 200 to activate the zoom interface 250. The user can double tap any area of the user interface 200, including any portion of the trend graph 230. The zoom interface 250 can display the portion in which the user double tapped in the user interface 200 to view the trend graph 230 in more detail. In some embodiments, when the system 100 displays the zoom user interface 250, the user can double tap the zoom user interface 250 to activate the user interface 200 and view the entire trend graph 230.

In some examples, the user can activate the zoom interface 250 by applying finger zoom gesture. For example, the user can touch the user interface 200 with at least two fingers and slide the at least two fingers apart from one another. This configuration can allow the user to gradually zoom in on a particular portion of the user interface 200 with a gradient zoom. The zoom interface 250 can be displayed gradually and can depend on the speed and/or extent of the finger zoom (for example, how far and/or how fast the user slides their fingers apart on the user interface 200). In some embodiments, the zoom interface 250 can display up to one month of data points. In some embodiments, the zoom interface 250 can display up to an hour, a day, and/or a year of data points. In some embodiments, the user can zoom out from the zoom interface 250 and activate the user interface 200 by pinching at least two fingers together. The seasonal variation interface 250 can be displayed gradually and can depend on the speed and/or extent of the finger zoom (for example, how far and/or how fast the user slides their fingers together on the zoom user interface 200).

In some embodiments, the user can navigate to various portions of the zoom interface 250. For example, the user can pan in any direction by swiping along the zoom interface 250. If the user pans too far to the edge of the zoom interface 250, for example, the zoom interface can indicate to the user that the user has reached the edge of the zoom interface 250. For example, at the edge of the zoom interface 250, the zoom interface can bounce back and/or rubber band.

FIGS. 6A-6C illustrate examples of the seasonal variation user interface that includes a varying number of data points of the user data 202. As shown in FIGS. 6A-6C, the user interface 200 can display one or more insights 206. The insights 206 can present to the user a general summary of the user data 202. For example, if no data has been recorded, the insights 206 can notify the user that no data is available (see FIG. 6A). In embodiments that include insufficient data, for example, when only one data point of the user data 202 has been measured, calculated, and/or recorded by the system 100, the insights 206 can notify the user that more user data is required (see FIG. 6B). In some embodiments, the insights 206 can remind the user to use the system 100 to monitor and/or measure user data. The insights can remind the user to use the system 100 to measure user data 206 more regularly, more often, and/or at different times.

In some embodiments, the system 100 can determine that a sufficient amount of user data 202 has been measured, calculated, and/or recorded. In some embodiments, the user interface 200 can display the user data within the trend graph 230 when a sufficient amount of user data 202, for example, at least two data points, has been measured, calculated, and/or recorded by the system 100. In some embodiments, the user interface 200 can display the user data within the trend graph 230 even when an insufficient amount of user data has been measured, calculated, and/or recorded by the system 100.

FIG. 6A illustrates an embodiment of the system 100 wherein no data is available. In this configuration, the user interface 200 can notify the user that no data is available to be displayed. For example, the insights 206 can present to the user that no data is available. In some embodiments, the trend graph 230 can present to the user that no data is available. For example, the trend graph 230 can display no data points of the user data 202. In such a configuration, the trend graph 230 can display text, an image, and/or another indication that no data is available. In this configuration, the trend graph 230 can display a range of years. The trend graph 230 can display a range of measurements on the horizontal and/or vertical axis.

In some embodiments in which no data has been measured, calculated, and/or recorded, the system 100 may not allow for a user to activate the zoom interface 250. In some embodiments, the system 100 may not allow for a user to apply at least some of the zooming gestures 254. In some embodiments, the seasonal variation user interface 230 does not display the user data 202 because of certain selections and/or filters selected by the user. For example, the user can select a specific activity, time period, physiological parameter, and/or filter for which no data has been monitored, measured, and/or calculated. In such configurations, the user interface 200 can notify and/or otherwise present to the user that no data is available within the particular filter selected.

FIG. 6B illustrates an embodiment of the user interface 200 wherein one data point 246 has been monitored, measured, and/or calculated by the system 100. In some embodiments, the one data point can be an insufficient amount of user data 202. In such configurations, the insight 206 can indicate to the user that an insufficient amount of data has been monitored, measured, and/or calculated by the system 100. In this embodiment, the data point is displayed on the trend graph 230. The data point can be displayed in the form of a line and/or a point. As shown in the trend graph 230, the data point can be displayed as a line that begins at the center of the graph, where the horizontal axis and the vertical axis intersect, for example, and extends outwardly to the ring indicating the value of the physiological parameter measured.

Some embodiments of the user interface 200 can display more than one data point. For example, FIG. 6C illustrates an embodiment of the user interface 200 including at least two data points 246. In some embodiments, at least two data points can be a sufficient amount of user data 202. In such configurations, consecutive data points 246 can be connected by one or more connecting lines 248. For example, the connecting lines 248 can be displayed connecting consecutive data points 246 at the point of the value of the physiological parameter 203. The connecting lines 248 can be straight or rounded. In some embodiments, the connecting lines 248 can be circular. In some embodiments, the connecting lines 248 can form a web-like structure. The area beneath the connecting lines 248 can be shaded towards a point at the intersection between the horizontal axis and the vertical axis disposed at the center of the trend graph 230.

In some embodiments, the connecting lines 248 can connect data points 246 recorded one, two, three, four, five, six, seven, eight, nine, and/or ten or more days apart. In some embodiments, the connecting lines 248 can connect data points 246 recorded 11, 12, 13, 14, 15, 16, 17, 18, 19, and/or 20 or more days apart. In some embodiments, the connecting lines 248 can connect data points 246 recorded one, two, three, four, five, six, seven, eight, nine, and/or ten or more weeks apart. Some embodiments a rounded connecting line 248 can connect two data points. In some embodiments, the system 100 can average two or more data points. In such configurations, user interface 200 can display connecting line 248 at the average of the two or more data points. In certain embodiments, the increment of the data points displayed by the user interface 200 in the trend graph 230 can indicate which data points are connected by the connecting line 248.

FIGS. 2A and 2B illustrate the top navigation bar 208 of the user interface 200. The top navigation bar 208 can be animated by the user interface 200. For example top navigation bar 208 can flip, spin, fade, and/or otherwise displayed with an animation. Top navigation bar 208 can include a title portion 220, a subtitle portion 224, stretch icon 216, a filter stack icon 218.

The title portion 220 can describe the type graph 204 that is displayed by the user interface 200. For example, the user interface 200 can display the trend graph 230. As illustrated in FIG. 2A, title portion 220 describes the type of graph 204.

The subtitle portion 224 can describe the type of filter selected and applied to user interface 200. For example, the user can select one or more filters from the plurality of filters, one or more physiological parameters, and one or more activities from the plurality of activities. By selecting the one or more filters, one or more physiological parameters, and/or the one or more activities, the user can access, by the system, a list of the plurality of filters, plurality of physiological parameters, and/or plurality of activities by selecting and activating the filter stack icon 218.

When the user selects the filter stack icon 218, the user interface 200 can display a filter user interface 260. FIGS. 5A and 5B illustrates an example of the filter user interface 260. The filter user interface 260 can provide a list of the plurality of filters, the plurality of activities, and/or the plurality of physiological parameters. The user can select one or more of the plurality of filters, the plurality of activities, and/or the plurality of physiological parameters. After selecting one or more of the plurality of filters, the plurality of activities, and/or the plurality of physiological parameters, the user can submit the selections by selecting a submit option. The system can receive the submission. The system 100 can update the data points depending on the user's selection and display a new version of the trend graph 230 in the user interface 200. In some embodiments, the system 100 dynamically updates the trend graph 230 according to the user's selections in real time.

In some embodiments, selection of the stretch icon 216 of the top navigation bar 208 can allow the title portion 220 to be displayed in the user interface 200 in full screen. In some embodiments, selection of the stretch icon 216 of the top navigation bar 208 can allow the title portion 220 to be displayed in the user interface 200 in the original configuration of the top navigation bar 208.

FIGS. 2A and 2B illustrate the bottom navigation bar 212 of the user interface 200. The bottom navigation bar 212 can be animated by the user interface 200. For example the bottom navigation bar 212 can flip, spin, fade, and/or otherwise be displayed with an animation. The bottom navigation bar 212 can include an information icon 226 and a share icon 228. In some embodiments, the system 100 can flip the bottom navigation bar 212 to reveal additional icons. Additional user interfaces can be accessed through selection by the user of the information icon 226 and/or the share icon 228, for example.

In some embodiments, the user can select the information icon 226 to access an information user interface 270. FIG. 3B illustrates an example of the information user interface 270. When the information user interface 270 is activated, the information user interface 270 can pop up from the user interface 200, overlap at least a portion of the user interface 200, and/or replace the user interface 200.

The information user interface 270 can include an explanation of the trend graph 230. The information user interface 270 can include instructions for interpreting trend graph 230. In some embodiments, the information user interface 270 can include a summary 272 of the display information including the trend graph 230. The summary can be scrollable in some examples.

In some embodiments, the information user interface 270 can include a list 274 of the plurality of physiological parameters 203. The information user interface 270 can display and/or highlight the one or more physiological parameters selected by the user. Each of the physiological parameters can be represented by an image and/or icon 275. In some embodiments, the information user interface 270 can include a list 276 of the plurality of activities. The information user interface 270 can display the one or more activities selected by the user. Each of the activities can be represented by an image and/or icon 277. In some embodiments, the information user interface 270 can allow the user to select the size adjustment icon 278. Selection of the size adjustment icon 278 can cause the size of the text to increase or decrease. In some embodiments, selection of the size adjustment icon 278 can cause the size of the images to increase or decrease.

The system 100 can include sharing capabilities. In some embodiments, the user can select the share icon 228 to access a sharing user interface 280 that can include a sharing menu with several options for sharing certain information to third parties. FIGS. 4A-4C illustrate an example of the sharing user interface 280. When the sharing user interface 280 is activated, the sharing user interface 280 can pop up from the user interface 200, overlap at least a portion of the user interface 200, and/or replace the user interface 200.

The sharing user interface 280 can allow the user to share information and/or a shared image 282 to third parties. The sharing menu can display a plurality of icons 285 representing third-party applications and/or websites for sharing the shared image 282 and/or other information. The plurality of icons can be displayed in rows, for example. The rows of icons can be scrollable in the left, right, up, and/or down direction to display additional icons. The user can select one or more of the plurality of icons to share certain user data and/or a shared image 282, as described below. For example, the shared image 282 and/or other information can be shared via digital or physical methods. In some embodiments, the shared image 282 and/or other information can be delivered to third parties through SMS, email, printing, and/or social media, among other sharing platforms. The sharing capabilities of the system 100 can allow the user to share the user data 202 with third parties, including a trainer, for example, who are invested in the user's athletic performance and success.

In some embodiments, the user data 202 can be shared as part of the trend graph 230. The sharing user interface 280 can allow the user to share a screenshot of all or a portion of the season variation user interface 200. In some embodiments, the sharing user interface 280 can allow the system to share an image 282 (see FIG. 4C) that includes all or a portion of the season variation user interface 200 and additional information. For example, the shared image 282 can include a view similar to the view displayed by the zoom user interface 250. In some embodiments, the shared image 282 can include a watermark 284 and a summary title 286. The watermark 284 can indicate a brand, for example. In some embodiments, the summarizing title 286 can display a summary of the filter and/or physiological parameter 203 selected by the user, for example. The shared image 282 can allow third parties to quickly view and interpret the user data 202 provided by the system 100. In some embodiments, the user can select certain data to be shared to the third parties. In some embodiments, the user data 202 can be shared in the form of raw data.

For example, the user can select a cancel icon 288 displayed by the sharing user interface 280. In some embodiments, the user can simply select an area outside of the sharing menu displayed by the sharing user interface 280.

III. Visual Elevation Infographic Display

FIGS. 7A-11C illustrate an embodiment of the user interface 300. The user interface 300 is similar or identical to the user interface 200 discussed above in many respects. Accordingly, numerals used to identify features of the user interface 300 are incremented by a factor of one hundred to identify certain similar features of the user interface 300. For example, as shown in FIGS. 7A and 7B, the user interface 300 can include a top navigation bar 308, one or more graphs 304, and a bottom navigation bar 312 as described above in connection with the user interface 200. The top navigation bar 308 can include a title portion 320, a subtitle portion 324, a stretch icon 316 and/or a filter stack icon 308. The bottom navigation bar 312 can include an information icon 326 that can be selected to display an information user interface 370 (see FIG. 8B) and a share icon 328 that can be selected to display a share user interface 380 that can include a sharing menu (see FIGS. 9A-9C) for providing sharing capabilities.

User data 302 can include one or more data points corresponding to one or more physiological parameters 303 as described above in connection with the user interface 200. The user interface 300 can include any one, or any combination, of the features of the user interface 200. For example, the user interface 300 can be substantially similar to the user interface 200. However, in some embodiments, the user interface 300 can illustrate an example of the user interface 200 in which the user has selected an elevation filter (see FIGS. 7A and 7B). To select a filter, the user can select the filter stack icon 318. When the system receives the request from the user, the system can cause the user interface 300 to display a filter user interface 360. FIGS. 10A-10C illustrate an example of the filter user interface 360. The filter user interface 360 can include a list of the plurality of physiological parameters 330 and/or the plurality of activities. FIG. 10B provides an example of the filter user interface 360 illustrating that the user has selected activity 366, but did not select activity 368.

In some embodiments, the user data 302 can be displayed in one or more graphs 304, such as a trend graph 330. In the illustrated embodiment, the trend graph can include an elevation graph. The trend graph 330 can provide a detailed look at all or a selection of the physiological parameters monitored, measured and/or calculated by the system.

The trend graph 330 can allow the user to view the user data over time. The trend graph 330 can allow the user to view the user data 302, such as the selected physiological parameters 303 at a particular elevation and/or during a particular time period. For example, the trend graph 330 can include a horizontal axis and a vertical axis. The horizontal axis can illustrate a specific time or a period of time. For example, the horizontal axis can display the date associated with each of the data points of the user data 302. In some embodiments, the horizontal axis can display the month and/or year associated with each of the data points of the user data 302. In some embodiments, the horizontal axis can display a range of minutes, hours, days, weeks, months, and/or years associated with each of the data points of the user data 302. The user interface 300 can display one or more horizontal axis labels. The horizontal axis labels can include narrow dates associated with a particular data point. The horizontal axis labels can include broader dates, such as a month and/or a year associated with the overall user data displayed in the trend graph 330.

The vertical axis can illustrate a specific elevation at which the user data 302 was monitored, measured, and/or calculated. The intersection between the horizontal and vertical axis can represent sea level in an example. The vertical axis can be incremented at constant elevation intervals. The vertical axis can be incremented at varying elevation intervals. The values of the vertical axis can be displayed in any unit, such as feet or meters, for example. the values of the vertical axis can be displayed in whole numbers in some embodiments. The unit displayed by the user interface 300 in the trend graph 330 can be dependent on a region where the user is located, for example. The unit displayed by the user interface 300 in the trend graph 330 can be dependent on a region set by the user device, for example.

The trend graph 330 can display each value of each data point of the user data 302. In some embodiments, the trend graph 330 can display a range and/or average of values for each time period displayed along the horizontal axis. For example, FIGS. 7A and 7B illustrate an example of the trend graph 330. The trend graph 330 can include one or more data bars 332 and one or more data values. The data bars 332 can be lines. In some embodiments, the data bars 332 can be rectangular and/or cylindrical, among other shapes.

The data values can be a value of each data point, a range of data points, an average of data points over a particular time period, and/or other metric calculated by the system 100 using the values of each data point of the user data 302. FIGS. 7A and 7B illustrate a standard display size of the user interface 300 (for example, without activating the zoom user interface 350). In this configuration, the average of data points over a particular time period can be displayed at an upper end of the data bars 332. When the system 100 receives a request from the user to activate the zoom user interface 350, for example when the user uses one or more zooming gesture methods disclosed herein, the system 100 can display the zoom user interface 350. For example, the user can use zooming gesture methods and/or features, such as a double tap, a finger zoom, and/or a pan, among other gestures. In some embodiments, panning can cause the zoom user interface 350 to have a parallex effect. In such a configuration, a background image, such as a mountain, can move more slowly than the trend graph 330. The parallex effect can advantageously allow the zoom user interface 350 to display the relevant information more clearly.

FIG. 8A illustrates an embodiment of the zoom user interface 350. The zoom user interface can display each value of each data point of the user data 302 disposed above the upper end of the data bars 332, for example, rather than an average. In this configuration, each value of each data point that is displayed can represent the value used by the system 100 to calculate a statistic, such as an average value displayed in the user interface 300. This configuration can advantageously allow the user to understand how the system calculated the statistic, such as the average value, displayed in the user interface 300. In some embodiments, the zoom user interface can display the statistic 338 near or adjacent to a group of values of each data point used by the system 100 to calculate the average value. The user interface 300 and zoom user interface 350 can advantageously allow the user to quickly and easily identify what user data is associated with an elevation change. The user interface 300 and zoom user interface 350 can advantageously allow the user to quickly and easily identify when individual data points or statistics calculated based on multiple data points increase as a result of an elevation change.

In some embodiments of the zoom user interface 350, the interface 350 can display the value of each data point in the same configuration as is displayed in the user interface 300 (for example, displayed within a shape 334 and/or with an animation). In some embodiments, to allow the user to more clearly view or access relevant information, the zoom user interface can display the group of values of each data point within a shape 336, as illustrated in FIG. 8A.

In some embodiments, the user interface 300 can be an interactive display. For example, when the user selects the elevation filter, the trend graph 330 can be displayed to the user by the user interface 300. When the trend graph is displayed by the user interface 300, the data bars 332 can dynamically extend upwards from the horizontal axis.

In some embodiments, the value of each data point of the user data 302 can be displayed at an upper end of the data bars 332 in various configurations. For example, as illustrated in FIG. 2A, the data value of each data point is displayed in a shape 334 such as a circle disposed at the upper end of the each data bar 332. The value of each data point can be displayed in a shape, such as a rectangle and/or square, among other shapes. Displaying the value of each data point in the trend graph 330 can allow the user to easily and quickly view and/or access relevant information. In some embodiments, the user interface can highlight the value of each data point in the trend graph 330 to allow the user to view and/or access relevant information more quickly. In some embodiments, when the trend graph 330 is displayed to the user, the shape surrounding the value of each data point and/or the value itself can swell, glow, become enlarged, and/or otherwise be animated to allow the user to view and/or access relevant information more quickly and easily.

Accordingly, the user would be able to quickly determine whether the user has experienced a change in elevation, when the user experienced a change in elevation, and how the change in elevation affected the user's physiological parameters. In some embodiments, the system 100 can automatically determine whether the user has experienced a change in elevation, when the user experienced a change in elevation, and how the change in elevation affected the user's physiological parameters. The user interface 300 can display this information in the elevation graph 330, for example. In some examples, the user interface 300 can display this information in one or more insights 306.

In some embodiments, the value of each data point is not displayed. In some embodiments the trend graph 330 does not include a shape that surrounds the value of each data point. In yet other embodiments, the trend graph 330 does not include any animation that highlights the value of the value of each data point.

FIGS. 11A-11C illustrate examples of the user interface 300 that includes a varying number of data points of the user data 302. As shown in FIGS. 6A-6C, the user interface 300 can display one or more insights 306. The insights 306 can present to the user a general summary of the user data 302.

FIG. 11A illustrates an embodiment of the system 100 wherein no data is available. In this configuration, the user interface 300 can notify the user that no data is available to be displayed. For example, the insights 306 can present to the user that no data is available. In some embodiments, the trend graph 330 can present to the user that no data is available. For example, the trend graph 330 can display no data points of the user data 302. In such a configuration, the trend graph 330 can display text, an image, and/or another indication that no data is available.

FIG. 11B illustrates an embodiment of the user interface 300 wherein one data point 346 has been monitored, measured, and/or calculated by the system 100. In some embodiments, the one data point can be an insufficient amount of user data 302. In some embodiments the one data point can be a sufficient amount of user data 302. However, the system 100 can encourage the user to cause the system to measure, collect, and/or calculate more user data 302. In some configurations, the insight 306 can indicate to the user that an insufficient amount of data has been monitored, measured, and/or calculated by the system 100. In this embodiment, the data point is displayed on the trend graph 330. The data point can be displayed as a single data bar 332 and corresponding data value. As shown in the trend graph 330, the user data 302 can be displayed by the trend graph 330 from left to right.

Some embodiments of the user interface 300 can display more than one data point in the trend graph 330. For example, FIG. 11C illustrates an embodiment of the user interface 300 including at least two data points 346. In some embodiments, at least two data points can be a sufficient amount of user data 302. In such configurations, consecutive data points 346 or groups of data points 346 can be displayed. In some embodiments, consecutive values of the data points can be averaged by the system 100. The user interface 300 can display the average value of the data points in configurations disclosed herein.

In some embodiments, the user interface 300 can include a summary dashboard. The summary dashboard can pop up from the user interface 300, overlap at least a portion of the user interface 300, and/or replace the user interface 300. The summary dashboard can display a summary of the user data 302 displayed in the trend graph 300. The summary dashboard can advantageously provide a summary to the user and/or be shared to third parties and can allow the user to access relevant information more quickly and easily. Accordingly, the summary dashboard can allow the user and/or a third party to help the user achieve enhanced performance by more easily and quickly adjust a diet and/or exercise routine.

In some embodiments, the summary dashboard can include several observations and/or callouts based on the user data 302 displayed in the trend graph 330. For example, the dashboard can display an average, mean, mode, and/or other statistic calculated based on data points representing a particular physiological parameter 303. In some embodiments, the system can determine and/or the summary dashboard can display any of the above-referenced statistics over various time periods, including seven, fifteen, and/or thirty or more days. In some embodiments, the system can determine and/or the summary dashboard can display an elevation the user must travel for one or more of the user's physiological parameters to be affected. In some embodiments, the system can determine and/or the summary dashboard can display the amount of time, for example the number of days, it takes for the user to acclimate to a new baseline at a different elevation. In some embodiments, the system can determine and/or the summary dashboard can display a length of time, for example the number of days, a variation in one or more of the user's physiological parameters lasts.

In some embodiments, the system can determine and/or the summary dashboard can display and/or notify the user of any changes in the user's physiological parameters. In some embodiments, the system can determine and/or the summary dashboard can display and/or notify the user of any particular elevations that affect one or more of the user's physiological parameters based on historical data. In some embodiments, the system can determine and/or the summary dashboard can display and/or notify the user of any particular elevations that affect one or more of the user's physiological parameters based on user data collected in real time. In some embodiments, the system can determine and/or the summary dashboard can display and/or notify the user of any particular elevations that affect one or more of the user's physiological parameters based on a comparison of user data stored in a records database. The records database can be remote from the system 100. In some embodiments, the system 100 can include the records database.

In some embodiments, the system can determine and/or the summary dashboard can display and/or notify the user of any particular elevations that affect one or more of the user's physiological parameters based on a comparison of user data measured during various activities.

In some embodiments, the system can determine and the summary dashboard can display and/or notify the user when a physiological parameter has reached a new high and/or new low. In some embodiments, the system can determine and the summary dashboard can display and/or notify the user when a physiological parameter is not generally optimal. For example, the system can determine and the summary dashboard can display and/or notify the user when any one of the user's physiological parameters is higher than an optimal physiological parameter. In another example, the system can determine and the summary dashboard can display and/or notify the user when any one of the user's physiological parameters is lower than an optimal physiological parameter.

In some embodiments, the system can automatically determine and display the physiological parameters and statistics disclosed herein.

IV. Visual Infographic Yin-Yang Display

FIGS. 12A-12C illustrate an embodiment of the user interface 400. The user interface 400 is similar or identical to the user interfaces 200, 300 discussed above in many respects. Accordingly, numerals used to identify features of the user interfaces 400 are incremented by a factor of one hundred to identify certain similar features of the user interfaces 200, 300. For example, as shown in FIGS. 12A and 12B, the user interface 400 can include a top navigation bar 408, one or more graphs 404, and a bottom navigation bar 412 as described above in connection with the user interfaces 200, 300. The top navigation bar 408 can include a title portion, a subtitle portion, a stretch icon and/or a filter stack icon. In some embodiments, the top navigation bar 408 can include a user profile 424 that can display a name and/or an image selected by the user. The bottom navigation bar 412 can include an information icon and a share icon.

The display information 401 of user interface 400 can include user data 402, such as one or more physiological parameters 403, and one or more graphs 404 as described above in connection with the user interfaces 200, 300. The user interface 400 can include any one, or any combination, of the features of the user interfaces 200, 300. For example, the user interface 400 can be substantially similar to the user interfaces 200, 300. However, in some embodiments the user interface 400 can be displayed in a different configuration than in user interfaces 200, 300.

For example, in the illustrated embodiments, the bottom navigation bar 412 can include a measure icon 414, a history icon 416, a team icon 418, and/or an option icon 420, among other icons. The measure icon 414 can be selected by the user to allow the system 100 to measure the one or more physiological parameters 403. In some embodiments, the user interface 400 can display that a user is measuring the physiological parameters 403. For example, the user interface 400 can display a signal waveform 422 within a widget (described in more detail below). In such configurations, the system 100 can push notifications in real time to the user and/or other users to notify the user and/or other users that a measurement is being taken. In some embodiments, the system 100 can push notifications in predefined intervals. The history icon 416 can be selected by the user to allow the user interface 400 to display a history of user data 402. The team icon 418 can be selected by the user to allow the user interface 400 to display user data of other team members. The options icon 420 can be selected by the user to allow the user interface 400 to display an options menu.

The user interface 400 can provide a user with an intuitive, easy and/or quick glance assessment of the balance of the user's fitness, goals, and/or wellness. Some embodiments of the user interface 400 can help to increase a user's usage of the user device by influencing the user. For example, FIGS. 12A-12B illustrate an example of the user interface 400. The user interface 400 can influence the user and provide an easily accessible comparison of one or more physiological parameters 403 by providing a plurality of graphs 430. Each graph 430 can correspond to the user and/or other users.

In some embodiments the system can allow a user to more easily understand the balance of the user's fitness and/or athletic value. The system 100 can calculate a metric, such as a numeric value, a physiological parameter, a percentage, a weighted value and/or a ranking. The metric can be calculated by the system 100 using various methods. For example, the system 100 can noninvasively measure one or more physiological parameters using methods disclosed herein. The system 100 can create an index for storing the user data 402, which include the one or more physiological parameters. In some embodiments, the index can represent a comparison of a readiness score, an intensity score, a resting heart rate, a regularity of taking measurements, and/or a frequency of taking measurements, for example. In some embodiments, the index can illustrate a comparison of one or more metrics calculated based on the user data 402 and an intensity score, a resting heart rate, a regularity of taking measurements, and/or a frequency of taking measurements calculated based on another user's user data.

In some embodiments, the user interface 400 can update and display the one or more metrics in real-time. In some embodiments, the user interface 400 can automatically update the one or more metrics at predefined intervals.

Each metric can be calculated using various methods. For example, the system 100 can calculate the readiness score by performing a weighted comparison of directly and indirectly measured values of each data point. The weighted comparison can be calculated by calculating a weighted comparison of a physiological parameter, such as a first of day tHb, a first of day respiration rate, a first of day pulse rate, a previous post workout capital tHb, a first of day SpO2, and/or a heart rate variability, for example, to an average physiological parameter calculated by the system 100 over a selected and/or predetermined period of time. In some embodiments, the weighted comparison can be calculated by comparing the physiological parameter to data collected by a third-party device and/or application, such as sleep and/or activity trackers. Overall, the readiness score can help to provide useful feedback to the user. For example, if the user has a readiness score of 95% calculated based on a consistently low pulse rate, low respiration rate, high tHb, full SpO2, and/or a healthy heart rate variability, for example, the readiness score can indicate to the user that the user is healthy.

In one example, the system 100 can calculate the intensity score by performing a weighted comparison of directly and indirectly measured values of each data point. The weighted comparison can be calculated by calculating a weighted comparison of physiological parameters measured during various activities, such as a post workout heart rate to a pre-workout heart rate, a post-workout SpO2 to a first of day SpO2, a post-workout respiration rate to a pre-workout respiration rate, a pre-workout tHb to a post-workout tHb, and/or third-party data such as bike power (watt-meters), running power (watt-meters), and/or stress scores collected from a third-party application such as activity trackers, for example.

The user interface 400 can display the metric and/or index calculated by the system 100. In some embodiments, the user interface 400 can display a comparison of one or more metrics corresponding to one or more users. For example the one or more metrics can be stored in a database, which can be a remote database. The system 100 can compare the metric between various data points of the user data 402 and user data of other users, such as teammates, friends, and/or celebrities, among other users. The user interface 400 can display the results of this comparison.

FIGS. 12A and 12B illustrate the user interface 400 that can display a plurality of graphs 430. In the illustrated configuration, the graphs 430 display a comparison of an average pulse rate value and an average total hemoglobin value. Each of the plurality of graphs 430 can be displayed by the user interface 400 in a shape of a divided circle, such as a Yin Yang widget. In the illustrated configuration, a first half 432 of the widget represents the average pulse rate value and a second half 434 of the widget represents the average total hemoglobin value. Each of the first half and the second half of the widget can allow the user to easily determine whether the user's metrics are balanced. For example, the graph 430B displayed by user interface 400 can represent a perfect balance. In the illustrated example, each of the first half and the second half of the widget are equal in shape. In some embodiments, the user interface 400 can illustrate unbalanced metrics. For example, graph 430A illustrates an unbalanced user profile. In these configurations the first half 432 and the second half 434 of the widget are not equal in size and shape.

In some embodiments, the user interface 400 can display images 438 associated with each metric displayed in each half of the widget to allow the user to more easily determine what metric is being displayed by the user interface 400. In some embodiments the outer rim 436 of the widget can be used to display certain metrics. For example a color can be displayed by the user interface 400 around at least a portion of the widget to display one or more metrics and/or physiological parameters.

Each of the first and second half 432, 434 of the widget can have at least one flag 440. The at least one flag 440 can be selected by the user. When the user selects the at least one flag, the user can influence another user, such as another team member. For example, when the user selects a first flag 440A of a second user's graph 430A, the system can send a notification the second user to encourage the second user. In some embodiments, when the user selects a second flag 440B of a second user's graph 430A, the system can send a notification to the second user to congratulate the second user. The system can encourage and reward a user's positive behavior by encourage participation between a plurality of users and/or facilitating interaction between a plurality of users. The users can socially reward other users and encourage other users to achieve a well-balanced lifestyle.

In some embodiments, the user interface 400 can display a graph 430B corresponding to a hero, professional athlete, and/or celebrity selected by the user. Accordingly, the user interface 400 can encourage the user to achieve a well-balanced lifestyle and/or enhanced performance by providing an easily accessible comparison to the hero. This can allow the user to more easily compare the balance displayed by the user's graph 430 to a goal balance displayed by the hero's graph 430B.

To view a widget in more detail, the user can select a particular graph 430. In some embodiments, the user can use the various methods for activating a zoom user interface 450, such as the zooming gestures disclosed herein. FIG. 12C illustrates an embodiment of the zoom user interface 450. The zoom user interface 450 can provide more detail and information than the graph 430 displayed in the user interface 400. In some embodiments, the zoom user interface 450 can display values and/or units of each of the metrics corresponding to the first half and the second half of the widget. In some embodiments, the zoom user interface 450 can display labels describing each of the metrics corresponding to the first half and the second half of the widget. In some embodiments, the zoom user interface 450 can display other information, such as a particular elevation at a particular location, a current location of the user, and/or an average elevation, among other relevant information.
